Ras Kanjas, you said:
---------------------------
Stop talking about millions of years........
...this is scientific theories, it's nonsence!
Nobody lived in Africa for millions of years as you said, because this planet Earth is not that old, seen?
---------------------------
Scientific theories nonsense? Do you really reject the discoveries of modern science?
I have never heard of Haile Selassie I rejecting science, Selassie I worked very hard to bring modern science and technology to Ethiopia. Just because science says the world is billions of years old does not mean that the Bible is wrong, it just means that not everything in the Bible is to be interpreted literally.
Geologists have used the radiometric dating of meteors and Moon rocks and have found that the Earth formed about 4.57 billion years ago. Our species, Homo sapiens, has been around for only 0.000001% of geologic time.
Radiometric dating is not nonsense.
The numerical age of rocks can be determined by radiometric dating. This is because radioactive elements decay at a constant rate. During radioactive decay, parent isotopes transform into daughter isotopes. The decay rate for a given element is known as its half-life, the time it takes for half of the parent isotope to decay. The ratio of parent to daughter isotopes in a mineral grain indicates the mineral's age. The radiometric date of a mineral specifies the time at which the mineral cooled below a certain temperature. Scientists can use radiometric dating to determine when an igneous rock solidified and when a metamorphic rock cooled from high temperatures.
The relative scale of geologic time is based on superposition and fossil succession. Bodies of rock are simply ordered from oldest to youngest. Isotopic and cosmogenic dating provide an absolute scale in which events are measured. Milankovitch cycles, reflecting periodic changes in aspects of Earth's rotation, provide another means of measuring absolute geologic time, and when effectively employed they yield quite precise ages.
Both the application of the molecular clock to modern human populations and occurrences of fossil skulls indicate that Homo sapiens (humans) evolved in Africa slightly before 150,000 years ago. Sophisticated tools, made of bone and stone, and are characteristic of Homo sapiens also appear fossil record of East Africa in sediments ranging from about 100,000 to 200,000 years. The oldest fossils assigned to our species are three skulls from Ethiopia that were described in 2003. Radiometric dating of associated volcanic rocks established the age of these fossils as 154,000 to 160,000 years. With the human fossils were advanced tools, including knives, and bones of hippopotamuses that the humans butchered.
